Abstract: A method for distinguishing between types of intraoral areas of interest (AOIs) includes receiving or generating a first 3D model comprising teeth; receiving or generating a second 3D model comprising the teeth; comparing the first 3D model to the second 3D model; determining a difference between the first 3D model and the second 3D model at a dental site comprising a tooth; determining an intraoral AOI that is associated with the difference; determining whether the difference comprises a first type of change indicative of a first type of intraoral AOI or a second type of change indicative of a second type of intraoral AOI; and responsive to determining that the difference comprises the first type of change, determining that the intraoral AOI is the first type of intraoral AOI and generating an indicator of the first type of intraoral AOI for the tooth.

Abstract: A system and method for post-processing of polymeric items having a liquid component and a predetermined heat deflection temperature is provided. The system includes a washing station to spray water at elevated temperature and pressure on the items while maintaining the temperature of the item below the heat deflection temperature. Then using a water distillation system to separate the water from the water mixed with the liquid polymer component by evaporating the water using heating coils with surface that is not conducive to adhesion of the liquid polymer component and then condense the water vapor into liquid water. The system may further include a spin station to separate the liquid polymer component by spinning the item. The system may further include one or more processing stations to rinse the item, dry the item, cure the item, remove the item from a tray to which the item may be attached and clean trays after removing the item. A conveyor system may be used to automate the post-processing of the items.

Abstract: Methods and systems are provided for manufacturing an appliance for correcting malocclusions of a patient's teeth. The method may include measuring the positions of a patient's teeth and receiving tooth movement constraints. The method may also include generating an initial treatment plan based on the measured tooth positions and the tooth movement constraints and measuring the malocclusions of the patient's teeth for one or more types of dental malocclusions. The method may also include generating a plurality of treatment plans from the initial treatment plan based on the measured malocclusion and generating a model of an appliance for each stage of the treatment plan. The method may also include generating instructions for fabricating the appliance for each stage of the treatment plan based on the model of the appliance for each stage of the treatment plan.

Abstract: A dental articulator includes a first arm hingedly joined to a second arm about a pivot axis, where each one of the first arm and the second arm are configured to mount a dental model comprising at least one measurement element, and an inspection tool capable of checking the at least one measurable element against allowable tolerances. Each arm includes a mounting bracket having a distal portion adapted to mount the respective dental model and having a proximal portion. Each arm further has a base member having a distal portion adapted to hingedly join the first arm and the second arm about the pivot axis. The inspection tool comprises a first measurement device and a second measurement device. The first measurement device is coupled to the first arm or second arm and the second measurement device is coupled to the first arm or second arm.

Abstract: Dental appliances having modified gingival edge profiles for optimizing orthodontic tooth movement. In some cases, at least a portion of the gingival edge is lengthened to extend past the gumline of the patient, thereby directing forces closer to a center of resistance of one or more teeth. In some cases, at least a portion of the gingival edge is shortened with respect to the gumline of the patient, thereby directing forces farther from a center of resistance of one or more teeth. The change in the force system of the dental appliance due to the gingival edge modification can be tailored and tuned for specific tooth movements.

Abstract: A system includes a heating section configured to heat a sheet of plastic to generate a heated sheet of plastic. The system includes a plate configured to secure a mold associated with a dental arch of a patient. The plate includes a locking mechanism. The mold includes feature configured to interface with the locking mechanism. The system further includes a thermoforming chamber configured to thermoform the heated sheet of plastic to the mold that is secured to the plate via an interface of the locking mechanism with the feature to generate a thermoformed sheet of plastic. The locking mechanism is configured to extend through the mold and overlap an upper surface of the mold to lock the mold in a z-direction that is orthogonal to a plane defined by the plate. The system further includes a cutting tool configured to trim an aligner from the thermoformed sheet of plastic.

Abstract: An intraoral scanner comprises a light source, a moveable opto-mechanical module, an axial actuator, and an image sensor. The light source is configured to generate light that is to be output onto an object external to the intraoral scanner. The moveable opto-mechanical module comprises integrated projection/imaging optics and an exit pupil, the projection/imaging optics having an optical axis, wherein the projection/imaging optics are entirely integrated into the moveable opto-mechanical module. The axial actuator is coupled to the projection/imaging optics and configured to move the moveable opto-mechanical module comprising an entirety of the projection/imaging optics in the optical axis to achieve a plurality of focus settings. The image sensor is configured to receive reflected light that has been reflected off of the object external to the intraoral scanner for the plurality of focus settings.
